The lamp-body is provided My invention relates to railway signalwith frames 1 23 4, secured in openings and lamps, and particularly to rotatablesignal- 1 adapted to receive different-colored lenses. 60 to lampsplaced on the topsof carsand adapted b represents the cover of thelamp-bodya,

In the roof is ofa car or caboose inany desired mandevice of this patent the lamp-body was supner,with anintervening washer of waterproof ported by a ring providedwith feet orlegs material. The upper end of the support 61 secured to the roof ofthe car or caboose and i has an inturned flange 01 and the base of theoperating-rod simply passed through the l the lamp-body fits within thisinturnedfiange 7o roof.

A rod 9 is conlamp-body provided'withsuitable lenses of nected at its. upper end to the diskl and exdifierentcolors, atubular cylindrical suptends down through the tubular support(1 port of cast met-a1 having one'end formed at to the interior of thecar and terminates in a an inclination and flanged for connection tohandle 10, by which the rod' and lamp-body 35 the roof of a car orcaboose and the other and arerotated. The rod 9 is fitted with a diskupper end with a notched inwardly-extendm, preferably divided intoquadrant surfaces i'n-g flange, the said lamp-body being con- 11, 12,13, and 14:, which are colored correnected to and fitting rotatablywithin the said spondingly to the colors of the respective support andthere being a connection from lenses and which in position upon the rod9 go do the said lamp-base to the interior of the car come directlybelow the lenses of. correspondf'or rotating the lamp-body. I alsoemploy a ing colors in order that the light being used stationary capcovering --the lamp-body and as a signal may be indicated from theinterior connected to thesupport for thelight or lamp of the car. Someof the parts heretofore deemployed within the lamp-body, and a stascribed are the same as those shown, de- 5 1' 5 tionary shield issecured to the lamp-support, scribed, and claimed in Letters Patent No.which shield: extends partially around said 584,110, granted June 8,1897, to O.

Fig. 2 is a elbow e. The cover ofthe lamp-body has a p raised integral portion 17 and a plate 18, andcentrally between these parts a sleeve 19 is employed, and these partsare preferably connected by solder. The extension 16 passes through theparts of the cover I) and the sleeve 19, and the position of theextension 15 at its free end is determined thereby and vertical movementprevented by a nut 20, the lower part of the extension 10 being adaptedto receive a lamp-socket 72-.

9 represents a shield partially surrounding the lamp contained in thesocket 7b. The shield is provided with an integral top 21 and may besecurely held in place by passing over the extension 16, between the nut20 and the lampsocket 7L; but I prefer to permanently connect the nut 20and shield together.

One of the sides of the lampbody may be convenientlyprovided with a door 1', by which access to the interior of thelamp-body is easily gained for the purposes of changing lamps orcleaning the reflector.

In the operation of the structure the extension 15, elbow a, tubularpart 16, shield g, nut 20, socket h, and lamp remain stationary andfixed, while the lamp-body, with the colored lenses, changes position asrotated by the rod 9 and handle 10, the position of the lampbody beingdetermined by the relative position of the colored disk m, ashereinbefore described.

I claim as my invention- 1. In a railway signal-lamp adapted for use onthe roofs of cars, the combination with a fixed support, of a revolublelamp body mounted thereon and adapted for varicolored lenses, means forrotating the lamp-body and for determining its several positions, acover for the lamp-body having a tubular portion forming a guide, astationary support for an incandescent or other lamp or light secured tothe roof of the car, a tubular extension thereof passing through the topof the lamp and means supported thereby within the lamp-body fordirecting the light through only one of the lenses thereof at a time.
